FILTER.

SPECIFICATION forming part of Letters Patent No. 637,686, dated November 21, 1899. y Aepiieetien met september 13898. serai No. 690.259. on model.)

may pass from the filteriinto a reservoir for use as needed, or asmall'quantity thereof may be forced backward through the ltering medium for cleansing the latter, or, when desired, the watenmay be drawn directly from the supply without` passing through the filtering medium, but contacting with the outer surface thereof, so as to iush the filter whenever straight or unfiltered water' is drawn.

One of the objects of my invention is to employ the same valve for controlling the flow` of water to the -filter and for drawing off the filtered water, a further object being to have the same valve also control the flushingpas sage, which is utilized for drawing water direct from the supply.

Another object of my invention is to provide certain improvements in the valve-operating mechanism whereby the same may be readily placed in any of the required positions and when released will automatically return to a predetermined normal position.'`

With these ends in view my invention consists in certain'features of novelty in the construction, combination, and arrangement of partsby which the said objects and certain other objects hereinafter appearing are attained,'all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a general view of my improved filter, showing the pipe which connects the filter with theV reservoir coiled in a cooling-chamber. Fig. 2 is adetail vertical section of the filter proper. Fig. 3 is an enlarged side elevation,`partly in vertical section, of ithe valve and valve-housing.

Fig. 6 is a vertical transverse section taken on the' line 6 6, Fig. 3. Fig. 7 is a vertical transverse section taken on the line 7 7, Fig. 3; and Fig. 8 is asimilar section to that shown in Fig. 3, illustrating a modification by which i the spring isprovided with antifriction-bearings, as will be hereinafter described.

In carrying out my invention I prefer to employ that type of filter in which water is filtered by being forced through an annular wall of filtrantmaterial-such, for instance, as a porous cylinder the interior of the cylinder constituting a chamber for receiving the filtered water, while the chamber containing the cylinder and the outer wall of the cylinder constitute a chamber for receiving the Water from the service-pipe or other supply.

1 represents the body of the filter-chamber proper, whose upper end is closed by -a removable cap 2, having a Iiange 3, secured to a ange 4 on the upper end of the body 1.'

Fastened between these flanges 3 4 is a plate 5, upwardly through which loosely passes a hollow rod or pipe 6, whose lower end is provided with a disk 7, rigidly secured thereto,

while the upper end of the pipe or hollow rod 6 is screw-threaded and provided above the plate 5 with a nut 8, so that the disk 7 and the rod 6 may be supported from the plate 5, and the filtrant-cylinder 9, which is located around the rod 6 and between the plate 5 and disk 7, may be securely clamped between such plate 5 anddisk vand the whole supported withinl the chamber 1 from the plate 5, gaskets 10 being located at the upper and lower ends of the cylinder 9, as will be understood. By this means it will be seen that I constitute two annular chambers-one,`

ll, surrounding the cylinder 9 and being the receiving-chamber for the unfiltered Water, While the other, 12, being within the cylinder 9 and constituting the chamber for the filtered water. The water to be filtered is admitted to the chamber 11 through an inlet-passage 13 in communication with pipe 14, as will be hereinafter more fully described, and after entering the chamber 11 oozes through the pores of the cylinder 9 into Vthe chamber-,12, in which it rises and compresses the airtherein upward into the cap 2, which constitutes a dome, the air being admitted to such cap through apertures 15 in the plate 5. When IOO the Water in the chamber 12 has risen as far ,v as a small aperture-16, formed` in the upper ,JIS

end of the pipe 6,itpasses downwardly through the pipe 6 and thence along a duct 17,for`m'ed in the disk 7, to a downwardly-extending tube n 18, which projectsthrough a suitable stuvfingbox 19 in the bottom ofv the chamber l and isl coupled by angelbow 20, having suitable pack- `ing-glands, to a tube 21, which leads to a threaded nipple 22 formed on the valve-housing 23l and surrounding aport 24 in such in a valve-plug 26, which is of the ordinary conical form, and fromsuch passage or Way 25- 28, formed in the valve-housing and surroundk.ed by a threaded nipple 29, having 'connection Withthe reservoir 27 by suitable pipe 30 and packing-gland4 3.1.' `If desired, the pipe c. 30 on its wayto the reservoir and at any suitable pointin its length maybe carried through a coolin-gror refrigerating chamber 32 for c'ooljingthe walter on its Way to and from the reservoir27.

the valve-plug 26 `is given about a quarter- Iturn, carryingthe handle `33 from the 'positionfshown in full lines in Fig. 4 to the `dotted E 1 position 33 and bringing a lateralport 34 in the'valve into Vcoincidence with the port 28,

thejreservoir.

munication with a flushing-passage, as I wilrl nowdescribe, so that the 'air confinedinthe dome 2 will forcethe l-tered Water in the chamber 12 backwardly through the ltrantcylinder 9 and into'the.,receiving-chamber11'., thus purging the poresof the filtrant-cylinder of all impuritiesl by'means of purefi-tered Water. The upperV side of the valve-housing 23 lis provided with a threaded Lneck 37, screwed. into they bottom of the 'chamber .1, andthe said impuritiescarried intothe chamber 11 by the. filtered water oozing back- `cati-nig with a'wa'y or passage 39,-.formed theplug or valve'2-6, as shown in dotted lines i in F-ig. Sand in sectionin Fig. 6, so that wlren the valve-plu g 26 `-isigiven a quarter-itu rn -f rom Thelower side lof the valve-housing ,j ust u-nconnected to the service-pipe, andits interiorI or what is preferably the normal position, a

Way or passage 44 in the valve-plug places the neck 42 in communication lwit-h a port 45 in the valve-housing, which leads to a threaded nipple 46 onthe side of the housing,and

this threaded nipple 46 is connectedv by the pipe 14 lto the inlet 13 at `the upper end of the casing 1. Theinletl is formed in aboss 13a on the sidev ofthe casing, which has a horizontal passage connecting the pipe l4with the inlet 13 and also connecting'with an Yair-inlet it passes on to' the reservoir 27 through-a port -valve 47, projecting upwardly therefrom and lhaving a downwardly-extending .air-supply pipe48, so lthat as the Water ru'shesinto'the.

vthe .receiving-chamber 11' percolates Jthrough .the filtrant-'chamber 9 into the cham-befr 12 and thence passes into ,the reservoir 27 via E the `eor'inections already described, the valve lWhen it is desired to draw filtered water,

being in the position shown `in the drawings, which is preferably'thenormal posit-in. j Should 'it be'desired to draw straight Water vorvvate1 iirect from the supply Without pass- E ing it vthrough the filtrant, thevalve-ihandle -33 i-fsgiven almost a half tur-n or revolution, `as 'shown A:at l33b in Fig. 4, so that the upper end of the way 44 Will be brought down v`in'tofoom-v l munie-ation with the port 43, such port y48 be'- ing oiset toione side, as-'shown in Fig. fZ, so

L6)`jto the left-hand side of the port or passage 38 Vand uncovers the port 40, sothat la free passageyis `,established between the receivingchamber ll'and the sink--pipe4l, vand at 'the sam-e time rthe way 25 i-nthe valve-plug =is`cut olf from communication with both ofthe Vports i 24128. Bythis means it will be :seen that the iiltrant-cylifnder 9 having been vpurgedlofin'r- IOO IIO

bf the valve-housing and having a socket 52, through which the reduced stem 53 ofthe valve-plug passes, and in which socket is located a spring or cushion 54 for holding the valve-plug tight. The members 49 50 of the spring-box are each provided with one-half of an annular casing 55, the members of the box being secured together by screws and flanges 56, and in this casing is located a coilspring 57, whose ends abut against abutments 58, formed one on each of the casing members. These abutments 58, however, have sufiicient space between them to permit of the passage of a lug 59, carried by an arm 60, formed on the hub of the handle 33 and projecting into the spring-casing through an annular slot 6l, so that when the valve-handle 33 is turned in either direction the lug 59 will compress the spring 57 away from the abutments 58 on one side and toward such abutments on the other side, and when the handle is released it will automatically return to its normal position, the ends of the springs 57 serving as a cushion for relieving the shock which might otherwise be caused by the sudden arrest of the lug 59.

In the modication shown in Fig. S I have provided the spring 57 with antifriction-bearings to relieve its friction in the casing. This consists of a pair of concentric rings 62 63, one arranged within and the other surrounding the spring 57 and each fitting approximately close to the inner and outer walls, respectively, of the spring-Casin g, which in this form is annular but square in cross-section, and interposed between each of the rings and such wall of the casing is a series of balls 64, seated in suitable sockets or grooves, so that when the handle is turned the rings will turn with it, and their friction will be relieved by the antifriction-balls. Inl this form of the invention the abutment for the ends of the spring 57 is constituted by two cross-bars 65, extending from side to side of the casing and on each side of the slot 66, through which the arm 67, corresponding to the arm before described, projects, the lug 59a, which compresses the spring 57, being arranged to pass between the abutments 65 and the slot 66 in this instance being formed in the outer side of the spring-casing, as will be understood.
